Overlooking the Royal Thai Sports Club—a rare patch of greenery in Bangkok’s urban jungle—the 227 elegantly appointed rooms here boast prime views, including a bird’s- eye view of the Sunday horse races. But the real highlight is the butler service: smartly suited assistants are on hand for everything from unpacking your bags to repairing a broken zip.

They can also arrange a lavish private breakfast, which includes caviar with poached eggs, mascarpone French toast, Champagne and a spicy bloody Mary. If you prefer your drinks in the evening, head to the St. Regis Bar, where at 6:45 p.m. each evening a sword-wielding butler sabers open a bottle of champagne.
